HEEL-BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 472,307', dated April 5, 1892. Application filed March 3, 1891. Renewed February 23, 1892. Serial No. 422,367. (No model.)

To all whom it may concern,.-

Be it known that I, FRANK MOLLOY, of Haverhill, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Heel-Burnishing Machines, of which the following is a specifica# tion.

This invention has for its object to provide a simple and efficient machine for burnishing 1o the heels of boots or shoes; and it consists in the several improvements which I will now proceed to describe and claim.

In the accompanying drawings, forming a part of this specification, Figure l vrepresents aside elevation of aheel-burnishing machine constructed in accordance with my invention. Fig. 2 represents an elevation of the opposite side of the same. Fig. 3 represents a top view of aportion of the machine. Fig. 4 represents zo a section on line 44, Fig. 3. Figo represents an end view of the portion of the machine shown in Fig. 3. Fig. 6 represents a top view of the sleeve which rocks or oscillates the shaft carrying the burnishing-tool. Figs. 7, 8, and 9 represent sections on lines '7 7, 8 8,

and 9 9, respectively. The same letters of reference indicate the same parts in all the figures.

My invention relates to the type of heel- 3@ burnishing machines in which the heel to be burnished is held in a fixed position and the burnishing-tool is oscillated about the heel, moving from the corner of the breast at one side around the heel to the corner of the breast 3 5 at the opposite side back and forth, and during said movement is moved progressively in a lateral direction, so that its burnishing action may commence at one end of the heel, as at the top lift, and extend gradually and auto 4o matically to the opposite end, as the heel seat or rand.

In the drawings, a represents the burnishing-tool, the shank a of which is fitted to move lengthwise in a socket b', formed on an arm b, which is aflixed to an arm c, project` ing laterally from a horizontal shaft el. The

burnishing-tool is normally pressed outwardly from the socket b by means of a spring e, Fig. 1, so that it bears with a yielding pressure upon the heel to which it is presented. 5o The arm b has a socketed sleeve b2, which receives the arm c and is attached thereto by means of a set-screw f. The arm c is rigidly affixed to the shaft d, and when said shaft is rocked in its bearings, as hereinafter described, the arm c and the tool-carrying arm b, together with the tool a, carried thereby, are osoillated, the tool being thus caused to move about the heel from breast to breast. The shaft CZ is journaled in bearings g g and 6o is provided at a suitable point with a lateral stud or arm d', on which is mounted a trunvdle-roll cl2.

h represents a sleeve, which surrounds the shaft d and is adapted to move endwise thereon. Said sleeve is provided with a spiral slot h', which receives the trundle-roll d2, said slot being of such width that its sides bear against diametrically-opposite points on the trundle-roll. The form of the slot h is 7o such that when the sleeve h is reciprocated on the shaft cl the bearing of the sides `of the slot on the trundle-roll causes the shaft d to rock or reversely rotate in its bearings.

i represents a guide, which is affixed to the same base m that supports the bearings g g. Said guide extends parallel with the shaft d and permits the sleeve h to reciprocate upon said shaft and at the same time prevents it from rotating with or upon the shaft. The 8o sleeve 7L is reciprocated by means of a wristpinj on a disk j', affixed to the driving-shaft 7c,which is journaled in bearings inabracket l, mounted on the supporting-base m, and a pitman n, connecting the wrist-pin j with a stud or pin o, affixed to the sleeve h. It will be seen that the rotation of the shaft lo and disk j causes areciprocating movement of the sleeve t through the wrist-pin j and pitman n, said reciprocating movement being con- 9o verted into a reversely-rotating movement of the shaft d and an oscillating movement of the burnishing-tool.

The above-described means for converting reciprocating into oscillating o1' reversely-ro- 95 tating motion constitute what is believed by me to be a new mechanical movement, which may be applied to other kinds of mechanism,

its use not being limited to heelburnishing machines. Said means are the most simple and desirable of any of which I am at present aware for imparting an oscillating motion to a burnishing-tool. lIence I consider their use in a machine of this class highly desirable.

To give the burnishing-tool the progressive movement above indicated, whereby it is caused to move from one end of the heel to the other While oscillating about the heel, I make the base on, which supports the bearings of the shaft d, movable horizontally between fixed guides q q on a fixed support p. On said pedestal or support p is mounted a fixed arm p', to which is pivotally connected one end of a pitman r, the other end of which is connected with an adjustable wrist-pin fr', secured to the outer face of a worm-gear s, which is loosely mounted upon the drivingshaft 7.1, so that it is adapted to rotate independently of said shaft, the connection between said gear .S and the shaft bein g shown in Fig. 5 as a pin s', inserted in one of the bearin gs in which the driving-shaft rotates and entering a peripheral groove in a hub formed on the gear s. The gear s is supported by the shaft 7c only as a matter of convenience, and it may equally well be supported by an independent stud or bearing, the rotation ot' the shaft having no effect upon the gear s.

t, Figs. 3 and 5, represents a gear affixed rigidly to the shaft k and meshing with another gear or pinion t', atlixed to a short shaft u, which is jonrnaled in a bearing u', affixed to the sliding base m.

u2 represents a beveled gear affixed to the shaft u and meshing with a like gear a3, atfixed to a shaft a4, which is journaled in bearings ui u, formed on a bracket 21,6011 the sliding hed m. To the shaft a4 is aiiixed aworm al, which meshes with the worm-gear s. The gears t a2 as are so proportioned that they impart to theshaftu4 from the driving-shaft L a slow rotary movement, which is imparted by the worm al to the gears. The rotation of the gear s causes a slow revolution of the wrist-pin i" thereon, and as said wristpin is connected by the pitman o' with an immovable support-viz., the fixed bracket p-it follows that the rotation of the gearscauses the slid ing base m, together with all the mechanism carried thereby, including the shaft (l and the burnishing-tool thereon, to reciprocate slowly in a direction lengthwise of said shaft, thus carrying the burnishing tool slowly across the heel back and forth from the toplift edge to the heel seat or rand edge as long as the machine continues in operation. It will be seen, therefore, that the tool is presented to all parts of theheel bythe combined movements resulting from its oscillation about the heel and its progressive movement across the same.

It will be observed that the mechanism for giving the tool the progressive movement across the heel is simple and effective and not liable to get out of order, the entire organized machine constituted as above described bcing as a whole simple and durable in its con struction and efficient in its operation.

The jack which supports thc boot or shoe may be of any suitable construction, and as I have notrepresented any construction of jack that is new with me I do not deem it necessary to describe the construction of jack here shown, as the same is well known.

The wrist-pin r on the side of the gear s is adjustable toward and from the center of rotation of the said gear, so that its throw may be increased or decreased, thus varying the length of the reciprocating movement of the bed or slide on. To this end the wrist-pin is fitted between two guides s' .5", affixed to the outer side of the gea-r s, said guides being beveled or recessed at their inner edges to receive a corresponding head or enlargement on the inner end of the wrist-pin 7". The wrist-pin is provided with a nut r2, which when loosened permits the wrist-pin to be adj usted between the guides s s and when tightened secures the wrist-pin rigidly to said guides.

It is obvious that the wrist-pin may be applied to a separate disk affixed in any suitable way to the gear s, it being immaterial whether the wrist-pin is engaged directly with the outer side of said gear or not so long as it is adapted to be revolved by the rotation of said gear.

I claiml. The combination, with a rock-shaft having a tool-carryin g arm, of a burnishing-tool, a sleeve surrounding said rock-shaft and provided with a spiral slot which receives a stud or roll projecting from the rock-shaft, a guide independent of the rock-shaft, in which said sleeve is fitted to reciprocate in a direction parallel with the rock-shaft, and means for reciprocating said sleeve and thereby causing the rock-shaft to rock or oscillate through its engagement with the spiral slot, the reciprocating movement of the sleeve being shorter than the length of the slot, whereby the slot is kept in continuous engagement with the stud and caused to oscillate the rockshatt, as set forth.

2. The combination of a jack to hold a boot or shoe, a slide or bed movable on a fixed sup* port toward and from said jack, a rock-shaft mounted in bearings on said slide and provided with an arm carrying a burnishing-tool, a sleeve surrounding the shaft and provided with a spiral slot receiving a stud affixed to the rock-shaft, a guide affixed to said slide or bed and engaged with said sleeve, whereby the sleeve is permitted to move endwise on the rock-shaft Without rotating, a drivingshaft mounted in bearings on the slide or bed, connections between the driving-shaft and the sliding sleeve, whereby the latter is reci procated and caused to oscillate the tool, and means, substantially as described, for slowly TOO IIO

reciprocating the slide or bed and the rocksllaft and oscillating tool carried thereby, as set forth.

3. The combination of the slide or bed, the rook-shaft mounted in bearings on the said slide and provided with an arm having a burnishing-tool, a drivin g-shaft mounted in bearings affixed to said slide, means for imparting a rocking motion from said driving-shaft to the rock-shaft and thereby oscillating the tool carried thereby,aloose gearor disk mounted on a support on the slide or bed, connections between said gear and the driving-shat`t,whereby the gear or disk is slowly rotated, and a pitman connected at one end with a Wristepin on said gear or disk and at the other end with a iiXed support, whereby the rotation of the gear or disk is caused to slowly reciprocate the slide or bed and the rock-shaft and oscila lating tool carried thereby, as set forth.

4. The combination of the slide or bed, the

tool-carryin g rock-shaft, and the drivin g-shaf t supported thereby, means, substantially as described, for imparting motion to the rockshaft from the driving shaft, a worm -gear mounted on a support on the slide or bed, a wrist-pin adjustably mounted on said gear, a pitman connecting said wrist-pin With a iixed support, a shaft having a worm mountedin bearings on the slide or bed and engaged with said Worm-gear, and connections, substantially asdescribed, between the worm and driving-shaft, whereby the worm is rotated, as set forth.

. In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 20th day of January, A. D. 1891.
